I think the underlying purpose is expression. It's not about technique, it's not about hitting the right note, writing the perfect prose, having the perfect brushstroke. It's about expression of oneself, the things around you, and the emotions. I think expression is the one word that I would use, whether it's for sorrow, tragedy, joy, or even the need to express and be heard.
Charlie AlbrightI actually think that many of the musicians who have something meaningful to say don't win competitions. An incredible pianist like Horowitz had so much to say, but he might not win anything in competition because of his wrong notes.
Charlie AlbrightIf you play it safe, middle of the road with all the right notes, you might win. If you are unique and have too much personality, you might easily score a '0' in competition.
